Casting to void* instead of void** cures the problem. As the cast is used to 'remove' the type from a variable, and not to change it, I would consider it a justified change. I don't think there will be consequences for the validity of the optimization. > Does anybody who knows gcc or the C standard better than I > know another solution? Code will have to be changed regardless, as it's not the function invocation but the cast itself that triggers the warning.
